Description
Technical field
The present invention relates to granulator, especially relate to a kind of granulator shear pin release mechanism, belong to food and feed technical field of processing equipment.
Background technology
Granulator has a shear pin usually, and for the protection of some parts such as ring mould, pressure roller, main shaft, gear drive or belt drives, avoid being damaged by overload in granulation process.The reason of overload is the jaws that impurity enters between mould and roller, also may be transship because feedstuff is difficult to granulation.According to the size of granulator, usually can select one, two or three shear pins, wherein the neck size of shear pin can strengthen the overload of bearing 150% to 200%.The granulator shear pin mechanism of prior art comprises:
1. be arranged on the fixing shear pin outer cover on granulator framework or gear-box.
2. be fixed on the shear pin flange of granulator main shaft end.
3. shear pin is arranged on axis or the radial position of outer cover and flange usually, and shear pin neck is between outer cover and flange.
4. granulator shear pin mechanism is arranged on the main the tip of the axis of granulator usually, is open end, so that take out the shear pin damaged fast.Lubricating wire is allowed to be connected to granulator main shaft end by rapid unhooking device or swivel head at open end.When the overload occurs, flange is followed granulator main shaft and is rotated, and is exposed in the danger of rotary flange by operation or attendant, and the flange of this rotation likely can be wound into operation or attendant's clothing protects hair, brings personal injury.
In granulator industry, the design of open end is adopted widely, but this violates the nearest North America safety standard new with Europe promulgation.How to design and a kind ofly meet new safety standard, avoid granulator main shaft end to be directly exposed to outside granulator shear pin release mechanism is those skilled in the art's problem demanding prompt solution always.
Summary of the invention
The object of the invention is the deficiency existed for prior art, provide a kind of granulator shear pin release mechanism meeting the new safety standard in North America and Europe, the main the tip of the axis of granulator is closed, and when shear pin is cut off, granulator can quit work.
For achieving the above object, the technical scheme that granulator shear pin release mechanism of the present invention adopts is:
A kind of granulator shear pin release mechanism, comprise granulator support or gear-box, described granulator support or gear-box are provided with the shear pin outer cover that granulator main shaft runs through, shear pin flange is coated with at the end face of shear pin outer cover, described shear pin flange is fixedly connected with granulator main shaft, some shear pins are provided with between shear pin flange and shear pin outer cover, shear pin outer cover is provided with the travel switch of monitoring shear pin flange rotary, described travel switch is connected with the power control unit of granulator, shear pin flange is subjected to displacement granulator and quits work, described shear pin outer cover is hinged with the guard shield covering main shaft end.When the overload occurs, shear pin is cut off, the shear pin flange of granulator main shaft and granulator main shaft end follows the ring mould rotation of granulator, travel switch detects the displacement of shear pin flange, the power control unit of granulator stops granulator work, ring mould and granulator main shaft stop the rotation, improve the security performance of granulator, prevent operation or attendant from being injured by the shear pin flange rotated, the shear pin flange closure that guard shield can will rotate after overload, the shear pin flange avoiding rotation contacts with operation or attendant, further increase the security performance of granulator, even if travel switch goes wrong, guard shield still can carry out closed protective to granulator main shaft end.
Described guard shield is while hinged with shear pin outer cover; another side is connected with shear pin outer cover by clamp; clamp place is provided with the travel switch detecting guard shield and whether open, and travel switch is connected with the power control unit of granulator, and guard shield is opened granulator and quit work.Whether travel switch is herein opened for detecting guard shield, if guard shield is in an open position, granulator can not start.
The lubricating rotary head for connecting lubricating wire is connected with at the main the tip of the axis of granulator.Profit is changed rotary head connection lubricating wire and is carried out lubrication cooling to granulator main shaft.
Described guard shield is provided with the slot that lubricating wire passes through.Lubricating wire can be connected with lubrication rotary head by slot, and guard shield both can carry out closed protective to granulator main shaft end, allows again lubricating wire to carry out lubrication cooling to granulator main shaft.
The middle part of shear pin offers groove, and this groove is at the counterface place of shear pin flange and shear pin outer cover.
The counterface place of shear pin flange and shear pin outer cover, leaves gap between the two end face, and the width of gap and shear pin central slot is suitable.
The present invention compared with prior art, has the following advantages:
Main for granulator the tip of the axis and shear pin flange closure can get up by guard shield, even if shear pin is because overload is cut off, granulator main shaft and the shear pin flange of rotation are also had no chance and to be operated or attendant contacts, and improve the security performance of granulator.Shear pin is cut off when the overload occurs; the shear pin flange of granulator main shaft and granulator main shaft end follows the ring mould rotation of granulator; travel switch detects the displacement of shear pin flange; the power control unit of granulator stops granulator work; ring mould and granulator main shaft stop the rotation; further improve the safeguard protection performance of granulator, prevent operation or attendant from being injured by the shear pin flange rotated.By frame for movement and electronically controlled dual security protection, in case the granulator main shaft of spin-ended turn, shear pin flange contact with operation or attendant, make to adopt granulator of the present invention can meet the new safety standard of North America and Europe promulgation.
